AUTOMOBILE-JACK.

Specification a Letters, Patent.

Application filed March 14, may Serial 1%. 222,447.

ToaZZ whomz't may concern v Be it known that I, Er.r GQUGHiJGR, a

citizen of the United States, residing at.

Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Automobile-Jacks, 1

of which the following is a specification.

This invention relates to jacks, and more particularly to jacks for supporting automobiles to relieve'the. tires of the weight the vehicle. I i

The object of the invention is to provide a simply constructed and eflicient jack of 'this character which can be quickly and easily applied and which is self-supporting when in use. I:

Another object is to so construct a jac that it may be readily adjusted for use in connection with vehicles having wheels of different diameters.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation of a jack constructed in accordance with this invention, with the parts in the position they assume when in use,

Fig. 2 is a similar view taken from the opposite or inner side,

Fig. 3 is a front elevation showing a jack in position ready to be lifted for elevating the wheel, the wheel being shown in dotted lines,

Fig. 4 shows a similar view of the jack in operative position and the wheel raised,

Fig. 5 is a detail side elevation of the upper portion of the lifting arm showing a slightly different form of the invention, and

Fig. 6 is a transverse section taken on the line 66 of Fig. 5.

In the embodiment illustrated, the jack constituting this invention comprises a lifting lever 1 in the form of a plate having one edge out out as shown at 2 intermediately the ends thereof to provide an arm 3, the cut out portion providing for the lifting of the lever into operative position without interfering by engagement with the hub of the Patented Aug. 6, 191 .8.

wheel in connection with which it isto be This lever l is, provided on its inner face at its loweredge with a thickened rib-like portion 4 which is here shown in the form of a cleat secured to the inner face of said lever, although obviously when the jack is made of metal, this, boss or rib will be cast integral with said lever. It is to be understood that' thej ack may be composed of any suitablematerial either wood or metal. A; liftlng arm 5 is. hingedlyconnected at one endto thelever 1 adjacent the rib 4 and is 7 designed to open outwardly to position it so t at i s pper or out end willbe disposed;

beneath the hub H of a wheel W as is shown clearly in Fig. 3. This arm 5 has its free end curved as shown at 6 to form a seat to receive the hub H so that when the jack is in use there will be no danger of the hub slipping off the jack. This seat 6 is preferably lined with rubber or other suitable anti-friction material to avoid marring the hub of the wheel.

To adapt this jack for use in connection with automobiles having wheels of different diameters, the seat 6 shown in Fig. 5 is made adjustable vertically to lengthen or shorten the lifting arm 5, said seat being preferably constructed of rubber and mounted on a block 7 which has a plurality of rods or pins 8 extending therefrom and which are designed to enter sockets formed in the upper end of the arm 5. A plurality of re movable spacers 9 are designed to be strung on these rods 8 to lengthen or shorten the arm 5 as desired.

The lifting arm 5 which is shown hinged to the lever 1 may be attached by any suitable form of hinge, a T-hinge being here shown, but obviously this is not the only form which could be used.

In the use of thisimproved jack, when it is desired to elevatean automobile from the floor to remove the weight of the vehicle from the tires, which is very necessary when storing a vehicle, or when it is not to be used for a considerable time, the jack is placed into the position shown in Fig. 3 with the lever 1 laid flat on the floor or earth, and the lifting arm 5 swungup with the seat 6 thereof extending under the hub H. The reinforced lower end of the lever is positioned adjacent the wheel as shown, and the reduced extension 3 which operates as a handle is then grasped by the operator and the lever lifted into the position shown in Fig. 3, which causes the lever 1 to be brought into contact with the lifting arm 5,

said lever and arm being then in parallel relation and in close proximity, the reinforced lower end acting as a support for the lever so that it will remain in upright operative position shown in- Fig. 4. It is of course, to be understood that one of these jacks is used in connection with each wheel. of the vehicle and whenit is desired to use the vehicle, all that is necessary is to grasp the handle 3 and swing the lever down into the position shown in Fig. 3 whereby the wheel IV is lowered and in a very few minutes the vehicle will be ready for use.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

A jack of the class described comprising a lifting lever having a lifting arm hinged at one end thereto and provided with a 1011- gitudinally extending socket in its free end, a rod adapted for insertion in said socket, a hub engaging seat carried by said rod, and spacers adapted to be strung on said rod for varying the length of said arm.

In testimony whereof I aflix my signature in presence of two witnesses.
